<p>Once a cursor has been initialized to refer to a particular key in the
database, it can be used to determine the number of data items that are
stored for any particular key.  The <a href="../../api_c/dbc_count.html">DBcursor-&gt;count</a> method returns
this number of data items.  The returned value is always one, unless
the database supports duplicate data items, in which case it may be any
number of items.</p>
